Life leading up to The Sims 4
In The Sims 4, Jamie started as an adult sim living in Willow Creek with his two children, Lily and Cody. The family has once again relocated to Willow Creek, and Cody has joined the family after moving in from living with his mother. Jamie begins in the culinary career and befriends an adult Summer Holiday, who happens to be his neighbour. The two start dating and before long they get married. Right after the wedding, the oven at the Dodger house sets on fire and risks Cody's life, however Jamie saves him and extinguishes it. After a short time, Jamie and Summer have their first son together, Cato.
Also in this time, his daughter Lily begins dating Malcolm Landgraab and they soon age into Young Adults together. The pair get married and have their first child, a daughter called Megan. Soon after, they have another son called Alex. Malcolm is caught cheating on Lily with Ella Landgraab and they divorce, their children staying with the mother.
Soon after, Jamie, as well as Summer, Lily, Megan, Alex, Cody, Cato and Ella (Jamie's final child with the unknown mother from Moonlight Bay) move into an apartment in the city of San Myshuno. Cody, who is now a Young Adult, meets Zoe Patel and starts a relationship with her, soon moving out after marrying her. They have four children, twins Leo and Lucy, Cedric and Landon.
